DIAMETER_REQ_T¶
Retrieves header information and AVPs from Diameter requests. AVPs can be retrieved by:
- Directly specifying the AVP codes in the form: DIAMETER.REQ.AVP( ). For example, to retrieve the Auth-Application-Id AVP (code 258), you can use the expression: DIAMETER.REQ.AVP(258).
- Using aliases that are provided for important AVPs. For example, the Auth-Application-Id AVP has the alias AUTH_APPLICATION_ID. So, the expression to retrieve the Auth-Application-Id AVP by using the alias is DIAMETER.REQ.AUTH_APPLICATION_ID.
General usage: DIAMETER.REQ.
This topic lists the expressions that are provided by this class.
Note: Expressions with the * symbol are inherited/promoted from diameter_message_t.
* ACCOUNTING_SUB_SESSION_ID
Returns the Accounting-Sub-Session-Id AVP (code 287) from the message.
Returns: avp_t
* ACCT_APPLICATION_ID
Returns the Acct-Application-Id AVP (code 259) from the message. Note: expression can be used to retrieve the value as Unsigned32
Returns: avp_unum_t
* ACCT_MULTI_SESSION_ID
Returns the Acct-Multi-Session-Id AVP (code 50) from the message.
Returns: avp_t
* ACCT_SESSION_ID
Returns the Acct-Session-ID AVP (code 44) from the message.
Returns: avp_t
* APPLICATION_ID
Returns the Application-ID from the message.
Returns: unum_text_t
* AUTH_APPLICATION_ID
Returns the Auth-Application-Id AVP (code 258) from the message. Note: expression can be used to retrieve the value as Unsigned32
Returns: avp_unum_t
* AVP_END
Returns the location at the end of Diameter message (or in other words end of all AVPs) in Diameter message.
Returns: text_t
* AVP_LIST
Returns the AVP region in Diameter message (or in other words returns location at start of AVPs and length equal to Diameter message length excluding header).
Returns: text_t
* AVP (uint avpcode)
Returns the specified AVP from the message. For example, to get the AVP with code 263 from a Request, use the expression: DIAMETER.REQ.AVP(263). Note: To get AVP that is nested inside a grouped AVP, use the AVP method from the avp_t class.
Parameters (expressions not allowed):
avpcode - AVP code
Returns: avp_t
* AVP (uint avpcode, uint vendorid)
Returns the specified AVP in given vendor-id namespace from the message. For example, to get the AVP with code 1001 and VendorId 10415 from a Request, use the expression: DIAMETER.REQ.AVP(1001, 10415). Note: To get AVP that is nested inside a grouped AVP, use the AVP method from the avp_t class.
Parameters (expressions not allowed):
avpcode - AVP code
vendorid - Vendor Id
Returns: avp_t

Returns the location at the start of AVPs (or in other words end of diameter header) in Diameter message.
Returns: text_t
* COMMAND_CODE
Returns the Command Code from the message.
Returns: unum_text_t
DESTINATION_HOST
Returns the Destination-Host AVP (code 293) from the request.
